Hot Water Cylinder Leaking

[Paulo663]

After some advice please. Just installed a new indirect vented copper cylinder and I've got a small weep from the cold water in Male iron 22mm x 1. I use plumbers tape wrapping the threads approximately 10 times.
I've just ordered a 1inch fibre washer, will the washer help and should I apply a larger number of plumbers tape.
Thanks I advance Paul
